Title: Electro rheological fluid composition
Inventor: FUJITA YASUNOBU
IPC: C10N30/02
Filed: 1993-02-02
Abstract: PURPOSE:To provide an ER fluid which is not limited in the kinds of fine solid particles and dispersion medium and can retain an ER effect for a long period of time without sedimentation of the fine solid particles even in an electric field-free state. CONSTITUTION:An electrical insulating dispersion medium is blended with fine solid particles and a thixotropic agent to prepare an ER fluid. Addition of the thixotropic agent forms a network structure in the ER fluid to impart thixotropic properties to the ER fluid. The network structure is broken by application thereto of an external shear force such as vibration or agitation, but restored to the original state to prevent sedimentation of the fine solid particles when the ER fluid is allowed to let stand.

Title: Printing-processing apparatus
Inventor: HASHIMOTO JUN
IPC: B41J2/52
Filed: 1997-02-20
Abstract: PROBLEM TO BE SOLVED: To provide a printing-processing apparatus which forms images of superior printing quality by smoothing lines, particularly stepped lines, and more specifically a printing-processing apparatus which can form printing images of high resolution without changing a resolving power of a printing head. SOLUTION: Image data to be inputted through a divider 38 are distributed to line buffers 39-42 for each line. Image data of three consecutive lines are subjected to smoothing. A boundary detection circuit 44 extracts, e.g. image data of three consecutive dots, judges whether eight dots are printed or not in the periphery of a central dot of the three dots as a target dot, compares data, e.g. with data of a preliminarily formed table, and smooths every pixel with the use of corresponding data. The process is carried out sequentially for each target dot, so that a smoothed image with few steps is formed.

Title: Comparator circuit
Inventor: TANAKA KOICHI
IPC: H03K5/08
Filed: 1987-02-18
Abstract: PURPOSE:To attain accurate setting of a threshold value of a comparator circuit by using a transistor (TR) of the same value as a resistance ratio so as to decide the bias of noninverting/inverting bias of an amplifier and providing a power ripple rejection circuit. CONSTITUTION:This circuit consists of a bias decision section 5, an amplifier section 6 and a ripple rejection section 7. A threshold voltage VTH is obtained as a difference between a noninverting bias V4 and an inverting bias V5. In designing the gate length and width of TRs T1-T4 the same, a value V6 is brought into a value of (1/2)V3 even with variance in diffusion. Similarly, the value V4 is expressed as (1/2)V2, and since no current flows to an input resistance RIN, the values V5 and V6 are equal to each other. The V2 and V3 are decided by the ratio of the resistors R1, R2 and R3, R4. Thus, the VTH is decided by the resistance ratio and the VTH with high accuracy not affected by the ripple because of the effect of the removed part 7 is obtained and the output of the comparator is obtained from an output terminal 4.

Filed: 1984-02-28
Abstract: PURPOSE:To assure the smooth running of an emergency vehicle by making it possible for a driver to surely recognize the approaching of an emergency vehicle and its direction even when the windows of his car are all closed and there is a radio or the like sounding in his car. CONSTITUTION:Based on the data programmed, a microcomputer 2 assigns to a band-pass filter 11 the first center frequency band which is characteristically high-level in the frequencies of emergency vehicle's sirens. Also it determines whether or not the signal level of a conversion circuit 10, which is to converse the input signal of the frequcncy band passing through the filter 11 to the digital amount corresponding to its level, is higher than the previously stored data. When it is higher, the next center frequency band is assigned to the filter 11. When the levels of all the assigned input signals are higher, it determines that an emergency vehicle is approaching, and makes an output device 3 operate.

Title: Incoming radio wave bearing measuring apparatus
Inventor: KIJIMA TAKESHI
IPC: G01S1/54
Filed: 1987-02-18
Abstract: PURPOSE:To achieve a smaller size, by calculating a scan cycle of a target radar from a peak time data of a reception power. CONSTITUTION:An amplitude value peak caught be a non-directional antenna 1 is detected with an AGC 2 (Automatic Gain Control), a detector 3 and a power peak time detector 4. A scan cycle of a target radar is obtained by determining difference from the preceding detection time with a scan cycle calculator 5. When a platform carrying the apparatus flies viewing a radar on the left, the scan cycle detected is enlarged. When the radar is viewed on the right, the scan cycle is shortened and error is zero when it is viewed at the front of the platform or opposite thereto. The bearing of the target radar can be specified by comparing a detection scan cycle with a data of a memory 6 using a comparator 7. This enables specification with one non-directional antenna thereby reducing the size.

Abstract: PURPOSE:To display the deterioration degree of lubricating oil and its change time by finding the mean value of the temperature of the lubricating oil in a constant time, by calculating the degree of deterioration according to the deterioration curve of the oil temperature of the lubricating oil to the time, and by integrating it. CONSTITUTION:Temperature sensor 1, provided to an engine, detects the temperature of engine oil and outputs temperature signal Vt.

The sampling period is set to (T2-T1)/n, and mean-value circuit 5 sums up (n) input signals Dt to calculate their mean value and outputs Dtheta as the representative temperature value in time (T2-T1). On the basis of the known deterioration curve, arithmetic circuit 6 calculates a deterioration time from obtained representative value temperature (theta) and outputs signal Dh. Arithmetic circuit 7 finds reciprocal U of the deterioration degree, i.e. dterioration time and arithmetic circuit 8 integrates U in sequence, so that the time when the sum reaches one is regarded as the time of an oil change.

Inventor: TSUKAMOTO TAKAHIRO
IPC: B41J2/485
Filed: 1984-03-01
Abstract: PURPOSE:To arrange so that clear prints may be obtained without printing irregularity between dots by forming the printing width of a printing element wider than the amount of head movement by one dot and overlapping prints in a dot-type printing device. CONSTITUTION:In the regulation of a control circuit, a head 8 is caused to move so that the amount of a head 8 movement by one dot is equivalent to one half the printing width of a printing element, and each printing element 10a is used for carrying out overlapped printing. A dot printing width A is twice as much as the amount of a thermal head 8 movement by one dot, so that a single dot is so designed as to consist of overlapped prints. Consequently, an overlapped portion is formed between the first dot 30 and the second dot 32. Thus dot print irregularity is eliminated and an oblique printing pattern shows an increased smoothness with resultant denser and clearer prints. Further, it is possible to print at low voltage and also drive a printer with a battery.

Title: Sc-mgo composite ceramic sintered compact and its production
Inventor: TAKENOUCHI TAKEYOSHI
IPC: C04B35/04
Filed: 1997-02-21
Abstract: PROBLEM TO BE SOLVED: To obtain a sintered compact having a high strength and high fracture toughness value and free from lowering of strength at a high temperature, by dispersing Sc particles having a specific particle size into MgO matrix crystal particles free from anisotropy or the crystal particles and crystal grain boundary and combining these particles. SOLUTION: MgO powder having 0.5-100μm particle diameter is subjected to wet mixing with Sc nitrate or Sc carbonate having 1.2-20μm particle diameter in a ratio of 1-20%. The mixture is heat-dried under reduced pressure by using a rotary evaporator and subjected to dry mixing. In sintering at normal pressure, the mixed powder is formed and then, the formed product is sintered at about 1250-1650 deg.C to provide the objective Sc-MgO composite ceramic sintered compact. The sintered compact strongly binds to Sc disperse particles at the interface and flexural strength is improved to about two times and fracture toughness is improved to about three times based on single phase material and hardly causes dispersion of characteristics. Furthermore, sintering is preferably carried out by normal pressure sintering or hot press sintering in vacuum or inert atmosphere.
